Tool Deburrs Both Sides of Holes
Whitney Tool will display the Burr-Zit tool, a product of the recently acquired Cogsdill Enterprises. Constructed from a single piece of M-2 high speed cutting steel, the clothespin-type deburring tool can deburr both sides of a drilled, punched or reamed hole in one operation, even when only one side is accessible. According to the company, users can deburr as many as 5,000 holes per grind with approximately six to 20 grinds per tool.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
